Thus a direct relationship between duration and price sensitivity is expected.
D. Since cash flows in the form of coupon interests are received prior to maturity, the
investor does not need to wait until maturity to recover the cost of investment.
Hence the duration of a coupon bond is generally smaller than its time to
maturity.
E. The duration is 0.5 years since the remaining cash flows (FV and final coupon
interest) are all received six months later when the bond matures and the present
value of the cash flows is equal to the cost of investment. Thus the duration of a
coupon bond is not always smaller than its time to maturity. It can be the same as or less
than the time to maturity.
F. Yes, this investment is riskfree since you are certain of the cost and terminal value of the
investment.
G. Assumption 1: The yield curve is flat at the time of bond investment. This
ensures that the expected return from the bond is the same return as its initial yield
to maturity.
Assumption 2: Any unexpected change in rates applies to the entire spectrum of
maturities, i.e., the yield curve experiences a parallel upward/downward shift.
This ensures that the unexpected rise (fall) in coupon reinvestment income offsets
the unexpected fall (rise) in the selling price of the bond completely.

income risks completely. 2...
